R290 environmental refrigerant

R290 is one of the best refrigerants available for mass production upto now: Negligible Global Warming Potential (GWP) and degradation time is considered in monthes, Zero ozone layer depletion potential (ODP); Permanent green, Less load for the same performance, Low energy consumption and higher efficiency.

*Comparison of refrigerant GWP values.

DHW tank disinfection

The DHW tank disinfection function is used to kill legionella by 65°C water to ensure the health and safety.
 

 

Climate curve

You can choose different climate correlation curves or your own customised curve. Once the curve is selected, the unit sets the outlet water temperature automatically according to the outdoor ambient air temperature.

Floor preheating and drying

Protect your home floor by activating the Floor Preheating function which slowly increases the heating temperature of the floor coils, avoiding possible floor damaging and transitioning smoothly to the heating function. The Floor Drying Up function provides an additional solution to the installer as it helps remove any residual moisture from newly installed floor coils, further protecting the installation and ensuring the optimal and effective operation of the heat pump.

Powerful heating with high efficiency

1. No capacity attenuation at -l0°C ambient temperature
2. Operation range down to -25°C
3. Maximum LWT reach 75°C 
4. Energy efficiency level: A+++
   

   

   

Mode combination

There are 4 single operation mode (Cool,Heat,DHW,Auto) and 3combined operation mode to meet different demands of using.

 

Fast DHW

You can select the Fast DHW Function for the unit to produce DHW when there is a need for immediate hot water production.

 

Additional control

1. Remote control for ON/OFFTBH,AHS
2. Balance tank temperature sensor(field supplied)ensures accurate water temperature control
